Elon Musk's xAI is now officially called SpaceXAI

Remember when Twitter was Twitter? Then Elon Musk bought it, renamed it to X, launched an AI company called xAI, which acquired X, and then Musk's space company SpaceX merged with xAI, which has now been renamed to SpaceXAI.

At some point, it may become practical to just lump it all together as "that Musk thing."

To clarify: SpaceX is the public company and the parent corporate entity that towers above it all; SpaceXAI is a subsidiary of SpaceX, and X is a subsidiary of SpaceXAI (there's another layer between these called X Holdings, but perhaps it's best not to complicate things any further).

The change, alongside a new logo for the company, has been announced on SpaceXAI's official X account, which has also been changed to @SpaceXAI.

SpaceX acquired xAI in February 2026, shortly before SpaceX's monster IPO in June, which immediately propelled the company to a valuation of roughly $1.8 trillion (it currently stands at about $2.1 trillion).

The acquisition was (officially) about Musk's idea of creating huge AI data centers in space. The company plans to start demoing Starmind (as this infrastructure will be called) in late 2027, with actual commercial deployment starting in 2028.

We'd never mention the fact that xAI was burning money and needed a wealthy parent company to keep it afloat.
